KNOCKDOWN PAPER BOX.

SPECIFICATION forming part of Letters Patent No. 340,915, dated April 27, 1886.

Application iiled June 28, 1852. ScrialNo. 65,017. (Model.)

To all 1071,0711, t may concern:

Be it known that I, JAMES G. HURD, acitizen of the United States, residing at Springiield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Knockdown Paper Boxes, of which the following is a specification.

This invention relates to improvements in that class of paper boxes known as knockdown boxes,7 the object being to provide an uncovered or live-sided box of this class capable of being instantly folded from a set-up to a flat position, and vice versa.

In the drawings forming. part of this specification,l Figure Iillustrates a box-blank from which a paper box embodying` my improvements is constructed. Fig. ll illustrates a blank from which a cover to said box is made. Fig. III represents a box folded iiat which was made from the blank, Fig. I. Fig. IV represents a flat-folded box-cover made from theblank, Fig. Il. Fig. V represents thebox, Fig. III, set-up; and Fig. VI, the cover, Fig. IV, in like position to the box, Fig. V.

In the drawings, A indicates the bottom ot' the box, 3 3 the sides, 4 the ends, and 2 2 2 the corner-aps thereof. 8 and 9 indicate the right-angle folding-lines of said box, and a a a a folding-lines running at an angle to lines 8 and 9.

B indicates the top ofthe box-cover, 5 5 and l2 l2, respectively, the sides and the ends thereof, and 6 6 6 6 its eorneriilaps. 10 and ll indicate the right-angleiolding-lines of said cover, and c c c c the folding-lines thereof, running at angles to said lines l0 and l1.

Said box and cover blanks are eut, in the usual manner, from anysuitable paper-board,

and the above-indicated folding-lines thereon are formed, as ordinarily, by scoring or indenting them,'to permit 0il properly folding the several parts of the blanks to form the objects for which they are intended.

To form the box lirst in a flat or knockdown form, as in Fig. III, the opposite corA ners of the two sides 3 3, outside ot' the lilies a, are folded upon said last-named lines, bringingsaid corners to lie upon said sides and the iiaps 2 to lie upon the bottom A. Cement is then applied to the upper sides of said flaps 2, and the ends 4 are folded upon said aps, and a proper lixing-weight is laid upon said ends until said cement has so dried as to unite the said flaps and ends.

In order to bring those parts of the sides 3 of the blank to which the iaps 2 are attached into such a position as will allow of eementing the ends et to the latter, so that the parts Lland 2 will occupy the requisite positions relative to each other shown in Fig. III, the` folding- 6o lines a are formed on said sides atan angle of forty-tive degrees to the lines 8 and 9.

lVhen it becomes desirable to set up the box, making itassnme the form shown in Fig. V, it may be done by simply pressing the sides 3 3 upward, or by drawing the edges of the ends l from each other, and the box is at once so prepared for the reception of its contents, no hooking of parts together being required, as in many knockdown boxes.

rIlhe cover-blank, Fig. II, is folded and cemented upon a similar plan to that employed in folding said box, but with the difference that the sides of the cover are made so that they incline to fold inward toward the top B, after the cover is iinished, while the sides of the box incline to fold or spring outward or away from the bottom A after the parts are folded and connected, as in Fig. III. Thus, when said cover is placed on the box, the former (3o-operates with the latter, by reason of the above-described inclination of box and cover to iold in opposite directions, to retain the box in an upright position when empty.

In folding and securing the said box cover in the dat position shown in Fig. IV, the corner-flaps 6 and those parts of the ends of the cover (l2) outside of the lines c c c c are folded on said lines, and the upper sides ofthe iiaps 6 are then cemented, and the sides 5.of the cover are next folded over upon said flaps, and there held in any convenient manner until said cemented parts firmly adhere to each other, when the cover takes the forni shown in Fig. IV, and is changed from the latter to that shown in Fig. VI by either bending up the ends 12 or drawing the sides 5 outward. In forming the folding-lines con said cover-blank they are made at an angle of forty five degrees to the lines l0 and ll thereon.

-What I claim as my invention is l. The herein-described blank for a paper box, consisting of the bottom and end parts, A et et, and the continuous side parts, 3 3, havsides or both ends provided with creases or scores extending obliquely across themV from corners to the upper edge, whereby the box may be knocked down at,snbstantia11y as described.
